A. Lange & Söhne Lange 1 Moon Phase “25th Anniversary” – Round Six

A. Lange & Söhne Lange 1 Moon Phase “25th Anniversary” – Round Six


The ceaseless birthday party of the Lange 1 gets its 6th celebratory watch, the Lange 1 Moon Phase “25th Anniversary”. As the ambassador of the Saxon brand, the Lange 1 is being regaled with ten exceptionally special watches, revealed individually consistently until October 2019. Blessing wrapped in the same silver and blue shading plan as the five going before models, this is the subsequent moon phase model in the anniversary line-up however with a twist. 

Celebrating the quarter century of the Lange 1

Like all the past birthday presents, the Lange 1 Moon Phase is a restricted version watch (25 pieces) decked out in a white gold case with blue details on the dial and special decorative twists on the development. The complete birthday package is comprised of 10 watches and commenced with this classic Lange 1 with a pivoted caseback , followed by Grand Lange 1 Moon Phase , the Little Lange 1 , the Lange 1 Tourbillon Perpetual Calendar (the most complex model up until now) and the Lange 1 Time Zone .

This anniversary is demonstrated on the 2017 Lange 1 Moon Phase, which in its day got another development (caliber L121.3) for the afternoon/night indication incorporated into the moon phase indication.

The ubiquitous moon

Whether you can see it or not, our celestial neighbor is always with us. Around evening time, and relying upon the current phase, the Moon stands out against the dark sky. In the daytime, the Sun usually manages to dominate the Moon and conceal her from our eyes, yet she is always there. A. Lange & Söhne wanted to portray the Moon’s omnipresent presence with this model and portrays the Moon during the daytime, against a brilliant blue sky, and around evening time, against a dark blue sky spotted with silver stars. Not simply a wonderful interpretation, this dual representation bends over as a day/night indicator, a helpful indication when setting the watch.  Like all Lange moon-phase models since first experience with the assortment in 2002, the accuracy of the patterns of the Moon is impeccable and will just need a one-day revision in 122.6 years.

A concentrate in blue

The white gold case is the same as the 2017 model and measures 38.5mm with a stature of 10.2mm, the sort of vital statistics that will seem like music to the ears of idealists. The layout of the dial has not been contacted and features the classic off-focused configuration and the emblematic Lange outsize date. As the 6th individual from the selective Lange 1 anniversary releases, certain details on the strong silver agenté-hued dial have been tweaked to separate it from the regular fare. The hour, minute, subsidiary seconds and force save hands are all thermally blued, the numerals are blue, the letterings on the dial are blue, the quantities of the date window are blue (notice the date is set at 25) and the evening and daytime skies of the moon phase work are also chosen in various tonalities of blue. Although the press pictures just show the starless daytime sky with a white gold moon ascending on the left, we are almost certain that the darker night sky will also feature the flawless laser-cut stars of its predecessor.

In a departure from the current model, all the iridescence has been peeled off the hands (hours, minutes and force hold). Indeed, even the small iridescent spots above the hour markers are currently blue, and the little triangular markers of the force hold gauge are portrayed in red and blue. As you would expect, the accompanying alligator strap is also blue with a strong white gold prong buckle.

Anniversary engravings on movement

Turning the watch over reveals the German silver three-quarter plate decorated with Glashütte ribbing and the hand-engraved balance cockerel. Much the same as the other “25th Anniversary” models, the balance chicken is specially engraved with blue accents along with the number ’25’ to help you to remember the auspicious occasion. The manual-winding caliber L121.3 is a derivation of the conventional Lange 1 caliber L121.1 of 2015. The 70 additional parts (total 438 components) for the moon phase and day/night indicator were integrated into the development in a particularly compact manner that the watch is just 0.4mm thicker than the L121.1.  Endowed with a twin mainspring barrel (subsequently the word Dopplerfederhaus imprinted on the dial) for a 72-hour power save, the escapement runs at a recurrence of 3Hz (21,600vph). Like all Lange watches, the watch is assembled not once, however twice!

The Lange 1 Moon Phase “25th Anniversary” is a restricted version of 25 watches and its cost is EUR 43,300. More information at .
